Module vocab 

2026-10-02: The step vocabulary: which steps each op’s pipeline has, in order, and the shape and spelling of each step’s value. The one table every requirement, declaration and rendering reads.

Owner: metrale-circuit (pipeline). Invariants:

• steps_of matches every OpKind without a wildcard arm, so a new op does not compile until its pipeline shape is defined.
• Projections (a linear of any role, the LM head, the router and both expert projections) share one shape; the routed gate/up projection adds the row gather by expert id.
